Atkinson valve
WebAssembled variable valve timing units (VVT) on assembly lines for Ford, GM, Audi, and Fiat-Chrysler o Learned about industrial manufacturing and implementation of lean manufacturing principles WebAn Atkinson cycle engine is of increasing popularity in hybrid powertrains, with a main aim of adjusting valve timing. Being similar to an Otto cycle, the Atkinson also leaves the intake valve open for a short time during compression stroke. Decreasing compression ratio to around 8:1 and lowers the pressure on the piston on the power stroke.

WebThe operation of the Atkinson cycle is depicted on a p - V diagram in Fig. 5.4. The cycle comprises the following processes: adiabatic compression 1 → 2, isochoric heat addition 2 → 3, adiabatic expansion 3 → 4, and isobaric heat removal. For this cycle, we have V2 = V3, p4 = p1, CR = V4 / V3, PR = p3 / p4, and TR = T3 / T1. Fig. 5.4.
